2Novel therapeutic diiminoquinone exhibits anticancer effects on human colorectal cancer cells in two-dimensional and threedimensional in vitro models显示文摘BACKGROUND Colorectal cancer(CRC) is the second leading cause of cancer-related mortality.Cancer stem cells(CSCs) in CRC, which are spared by many chemotherapeutics,have tumorigenic capacity and are believed to be the reason behind cancer relapse. So far, there have been no effective drugs to target colon CSCs. Diiminoquinone(DIQ) has shown promising effects on targeting colon cancer.However, there is limited research on the effects of DIQ on eradicating CSCs in CRC.AIM To investigate the anticancer potential of DIQ on colon CSCs in two-dimensional(2D) and three-dimensional(3D) models using colonospheres and patient-derived organoids.METHODS Various 2D methods have been used to assess the effect and the mechanism of DIQ on HCT116and HT29 cell lines including cell proliferation and viability assays, migration and invasion assays,immunofluorescence staining, and flow cytometry. The potency of DIQ was also assessed in 3D culture using the sphere formation assay and colon cancer patient-derived organoid model.RESULTS Our results showed that DIQ significantly inhibited cell proliferation, migration, and invasion in HCT116 and HT29 cell lines. DIQ treatment induced apoptosis along with an accumulation of HCT116 and HT29 cancer cells in the sub-G1 region and an increase in reactive oxygen species in both CRC cell lines. DIQ reduced sphere-forming and self-renewal ability of colon cancer HCT116and HT29 stem/progenitor cells at sub-toxic doses of 1 μmol/L. Mechanistically, DIQ targets CSCs by downregulating the main components of stem cell-related-catenin, AKT, and ERK oncogenic signaling pathways. Potently, DIQ displayed a highly significant decrease in both the count and the size of the organoids derived from colon cancer patients as compared to control and 5-fluorouracil conditions.CONCLUSION This study is the first documentation of the molecular mechanism of the novel anticancer therapeutic DIQ via targeting CSC, a promising compound that needs further investigation.Alissar Monzer Kevork Wakimian Farah Ballout Samar Al Bitar Amani Yehya Mariam Kanso Nour Saheb Ayman Tawil Samer Doughan Maher Hussein Deborah Mukherji Walid Faraj Hala Gali-Muhtasib Wassim Abou-Kheir 2022World Journal of Gastroenterology2022,28,33:1

15撒哈拉地台的地质和构造特征以及沉积盆地演化轮廓显示文摘在撒哈拉地台上,从南部的霍加尔山开始,可以观察到许多南北走的隆起(阿姨吉德尔比亚德-哈西边斯欧德,提克赫姆伯卡-扎尔扎伊廷-阿勒拉尔,伊贾伦-姆扎卡等),这些隆起之间是宽阔的复向斜,下伏许多与其同走向的坳陷。因此,东撒哈拉复向斜可以分为两个坳陷,南部是伊利济坳陷,北部是东大沙漠坳陷(古达迷斯坳陷)。中撒哈拉复向斜也下伏两个坳陷,其中,穆维迪尔坳陷位于南部,瓦德米亚坳陷们于北部。在西撒哈拉复向斜内发现了阿赫奈特、拉甘、廷杜夫、提米蒙和贝沙尔等缺陷(图1和2)。Guiraud等(1987)把这些盆地分为北撒啦 盆地和南撒啦盆地,而Legrand(1985)和Whiteman(1972)则对这些盆地的地层作了详细描述。Monzer Makhous 白振端 2001石油地质科技动态2001,,1:0

19Survival of rat sciatic nerve segments preserved in storage solutions ex vivo assessed by novel electrophysiological and morphological criteria显示文摘Most organ or tissue allografts with viable cells are sto red in solutions ex vivo for hours to seve ral days.Most allografts then require rapid host revascula rization upon transplantation to maintain donor-cell functions(e.g.,cardiac muscle contra ctions,hepatic secretions).In contrast,peripheral nerve allografts stored ex vivo do not require revascularization to act as scaffolds to guide outgrowth by host axons at 1-2 mm/d,likely aided by viable donor Schwann cells.Using current storage solutions and protocols,axons in all these donor orga n/tissue/nerve transplants are expected to rapidly become non-viable due to Wallerian degeneration within days.Therefore,ex vivo storage solutions have not been assessed for preserving normal axonal functions,i.e.,conducting action potentials or maintaining myelin sheaths.We hypothesized that most or all organ storage solutions would maintain axonal viability.We examined several common organ/tissue storage solutions(University of Wisconsin Cold Storage Solution,Normosol-R,Normal Saline,and La ctated Ringe rs) for axonal viability in rat sciatic nerves ex vivo as assessed by maintaining:(1) conduction of artificially-induced compound action potentials;and(2) axonal and myelin morphology in a novel assay method.The ten diffe rent storage solution conditions for peripheral nerves with viable axons(PNVAs) diffe red in their solution composition,osmolarity(250-318 mOsm),temperature(4℃ vs.25℃),and presence of calcium.Compound action potentials and axonal morphology in PNVAs were best maintained for up to 9 days ex vivo in calcium-free hypotonic diluted(250 mOsm) Normosol-R(dNR) at 4℃.Surprisingly,compound action potentials were maintained for only 1-2 days in UW and NS at 4℃,a much shorter duration than PNVAs maintained in 4℃ dNR(9 days) or even in 25℃ dNR(5 days).Viable axons in peripheral nerve allografts are critical for successful polyethylene glycol(PEG)-fusion of viable proximal and distal ends of host axons with viable donor axons to repair segmental-loss peripheral nerve injuries.PEG-fusion repair using PNVAs prevents Wallerian degeneration of many axons within and distal to the graft and results in excellent recovery of sensory/motor functions and voluntary behaviors within weeks.Such PEG-fused PNVAs,unlike all other types of conventional donor transplants,are immune-tolerated without tissue matching or immune suppression.Preserving axonal viability in sto red PNVAs would enable the establishment of PNVA tissue banks to address the current shortage of transplantable nerve grafts and the use of stored PEG-fused PNVAs to repair segmentalloss peripheral nerve injuries.Furthermore,PNVA storage solutions may enable the optimization of ex vivo storage solutions to maintain axons in other types of organ/tissue transplants.Liwen Zhou Monzer Alatrach Ted Zhao Paul Oliphint George D.Bittner 2023Neural Regeneration Research2023,18,9:0
